Accupro ACC-G038-8 Retaining Ring Grooving Tool

Product Description

The ACCUPRO ACC-G038-8 is a solid carbide internal retaining ring grooving tool designed for cutting precision grooves in bored holes. Built from submicron-grade solid carbide, it delivers consistent edge retention and dimensional accuracy in production and maintenance machining applications. The tool features a 5/16 inch shank diameter and a 0.0385 inch groove width, making it suited for tight-tolerance retaining ring seats in small-diameter bores. Machinists and toolroom technicians use this tool on CNC lathes and manual turning centers where groove geometry must be held to close tolerances.

This grooving tool is used in applications requiring internal retaining ring grooves in bores starting at a minimum diameter of 0.3120 inches. It supports a maximum hole depth of 0.5000 inches and has a projection of 0.1100 inches, giving it reach into shallow-to-moderate depth bores. Typical install scenarios include aerospace, automotive, and general precision machining environments where snap ring groove placement is critical to component retention and assembly integrity.

Key Features

• Submicron-grade solid carbide construction for extended tool life and edge stability
• 0.0385 inch groove width sized for standard retaining ring seat dimensions
• Minimum bore diameter of 0.3120 inches enables work on small, tight-clearance holes
• 0.1100 inch projection provides controlled reach without excess overhang
• 2.0000 inch shank length with 2-1/2 inch overall length for secure toolholder engagement
• 5/16 inch shank diameter compatible with standard collet and toolholder systems

Compatibility

Designed as a direct-fit replacement-style internal grooving tool for use with standard 5/16 inch bore-type toolholders on CNC and manual lathes. Verify toolholder bore size and projection requirements before installation.

Installation Notes

This tool is installed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and the toolholder is secure before seating the shank. Do not exceed the tool's stated minimum bore diameter or maximum depth of cut, as carbide tooling is brittle and susceptible to breakage under side loading or excessive depth. Use appropriate cutting fluid for the workpiece material to manage heat and chip evacuation.
